IMPROVEMENT IN SIGHTS FOR FIRE-ARMS.

Specification forming part of Letters Patent No. 25,389, dated September13, 1859.

To all whom it may concern:

Be it known that I, HENRY WV. CoLvIN, of the county of Pendleton andState of Kentucky, have invented and made certain new and usefulImprovements in Gun-Sights; and I do hereby declare that the followingis a full and exact description thereof, reference being had to theaccompanying drawings and letters of reference.

Figure 1 is afront view of the fore sight, as seen from the point H inthe line H A, Fig. 5. Fig. 2 is a side View of the fore sight, as seenin the line B B, Fig. 1. Fig. 8 is a front view of the hind sight, asseen in the line H P, Fig. 5. Fig. 4. is a side view of the hind sight,as seen in the line XX, Fig. 3. Fig. 5 is a side view of both sightsproperly arranged for use on the gun.

The nature of my invention consists in the sights being so arranged orconstructed that the marksman can take more certain aim in whateverposition the gun may be held, and to enable those whose eyes or sighthave be-, come dim by age or any other cause to take certain aim. V

In the construction of the fore sight, I employ a semicircular piece ofiron, or other metal, which is transversely fixed in the gun-barrel, asseen by the letter E, Fig. 5. In combination with this piece of metal Iuse a semicircular piece of silver, or any suitable metal, placed invertical position, and countersunk and firmly secured, but sufficientlyraised to form a head, the same being in direct line or range with thenotch P in the hind sight, and in the range H K, Fig. 5, and A A A, Fig.2, and A, Fig. 1.

In order to. obviate the well-known difficulty to marksmen commonlyknown as blazing or glaring of the sights, when the gun is held in anopposite direction from the sun, I employ two or more notches ortransverse sinks cut in the main sight, so as to produce a shade on thesemicircular piece of silver constituting the beadA, as seen in Figs. 1aucl 2, (represented by the letters E E.)

In the construction of the hind sight, which is of a triangular form,which is shaded by transverse sinks or notches, into which I insert therange or needle, which is of silver or any other suitable metal, whichis placed in an upright position immediately under the notch I, asrepresented by the line B P, Fig. 3, this needle being finelypointed,with the point upward, as seen in Fig. 3, and also in Fig. 4.The front of this sight is shaded by transverse sinks or notches,producing the same effect as they do in the fore sight, as seen in Fig.4, (represented by the lines and letters N N N,) also in Fig. 3, (by thesame letters.)

Having thus described my invention, Iwish it distinctly understood thatWhat I claim as my invention, and desire to secure by Letters Patent ofthe United States, is

The semicircularform of the fore sight,with its range piece or bead andshades, and the triangular form of the hind sight,with its needle orrange and shades, substantially as herein described, and for the purposeset forth.
